Two men and 7 women can complete a work in 28 days whereas 6 men and 16 women can do the same workin 11 days. In how many days can 7 men complete the same work?

Total work= TW=( 2M+7W) x 28 =(6M + 16W) x 11
56M+196W=66M+176W
10M=20W
M/W=2/1

Total work=(2x2+7x1)x28=308 units
7men can complete the work=308/7 x 2=22 days
